Ready to test your strength while building a monster-sized back? If so, this week’s badass workout has your name all over it. In this 4th installment, PJ Braun, president of Blackstone Labs and Prime Nutrition, ups the ante and the weight with a high-volume, routine that will get your back wide enough to slap a billboard on.

As demonstrated in PJ’s previous badass workouts, you don’t need to go heavy to get through a badass workout. However, in this back routine you do. Heavier loads combined with higher volume may make this the most brutal badass workout yet. Think you’ve got what it takes to fight through the pain and plow through this back attack? Then step up to the plates and show us what you’ve got.

This week’s badass workout is one hardcore and intense routine that presents an all-out assault on your entire back with a barrage of badass moves. Stay the course, and you’re done in 45 minutes. C’mon bro, you’ve got this!

The Workout

To be completed in 45-minutes, including warm-up (see all the moves in the video above).

Warmup: Start out with a warmup of close-grip lat pull downs with a neutral grip: 4 sets of 20 reps, less then 30-seconds rest per set.

Old fashioned T-bar rows in a corner: 4 sets of 8-10 reps with 30 seconds rest per set.

Giant Set:

You must fail between 12-15 reps per exercise with zero rest between exercises. All 3 exercises are done in that specific order before resting. Rest period after each cycle is 90 seconds. Perform the cycle for 4 total rotations.
